MetaMagic for Capture One.
Release history.
Capture One has its own release track, separate from Lightroom Classic and MetaMagic Desktop.
Protected client,
solid Capture One workflow.
Version 0.3.1 consolidates the Windows Capture One integration around stable XMP/IPTC write-back, automatic reload and the Capture One-specific Control Center.

Expanded metadata
and workflow fields.
The 0.2.x line introduced working Capture One Color Tags and Rating controls, then expanded write-back for IPTC Contact, Status and additional professional metadata fields.
Foundation
and XMP integration.
The first Capture One builds established AI generation, XMP sidecar write-back, GPS/location enrichment, MetaMagic AI Instructions and automatic metadata reload on Windows.
Native Mac build
coming later.
The current 0.3.1 package is Windows-only. The planned macOS client will share the same MetaMagic backend, account and Capture One Control Center while using a native Mac package.
